You can get pretty far using a bit of JS and Tamper Monkey . You can even search in existing user scripts if someone already did it.
For example, all of the list abstractions (map, filter, reduce, etc.) will copy the array to a new list every time you chain them.
This methods were added to generator recently. So you can avoid copying the array in memory.
All this is also without even getting started on the million JS frameworks and libraries which make it really easy to have vendor lock-in and version lock-in at the same time
In my opinion, it’s also what make JS good. There a package for almost everything.
I did a quick user script with Tampermonkey to search torrents links from torrents-csv.com of movies when I’m navigating to themoviedb.org . Not sure I can share it but it was really fun to develop and really useful for me.
Finally we have the Iterator Helper Methods!
I’m really happy with Mullvad and their pricing. I can pay for only one month if I need it so I don’t have another subscription to pay each month.
